Good idea or waste of time?

post #1 of 25
Thread Starter 
Hey guys, I've been thinking that to perhaps give me better temps on my cpu I need to rearrange my loop. Because as the water gets pumped through my loop, it looses it's pressure, which is why I think cpu temps aren't that great.

Currently I have my loop going:
Pump/res>gpu>rs360>cpu>rs240>pump/res

What i'm thinking about doing:
Pump/res>cpu>rs360>gpu>rs240>pump/res

My thought is that doing it this way will provide better flow/pressure through the cpu block, and decresing the temps. Gpu temps aren't as big of a deal, which is why I think putting it farther back in the loop would be okay. Would this really work? Or is my logic wrong?

From what I have heard... loop order doesn't matter in the long run. The water temps all become the same temps. So you will have cooler CPU temps in burst at the beginning, but in the long run nothing will be different.

Should it be res then pump?

I'm not talking about trying to go to a radiator and then whatever i'm trying to cool, i'm talking about pump efficiency when it goes through the loop.

Because the pump has to be loosing pressure as it goes through my gpu then 360 rad. Or at least that is what i'm thinking. Does anyone have an answer to my question?

I would probably swap the 360 and the 240 in your current setup or else go to the CPU first though, because the GPU will put out more watts of heat than the CPU will. However, I would only do that if you were planning on tearing it apart. In the grand scheme of things it won't help a lot.

I run my to my CPU first and then into a 120 then into my GPUs which then go to a 240. GPUs are designed to run a little hotter and mine tops out at 46° on a furmark. Still far under anything I would need to worry about as 90° is what you will see on air. So yeah, the CPU should be cooled first in my opinion just because its max operating temp is lower than any GPU you will find.

I'd be willing to have my gpu temps increased a little bit for my cpu temps to go down. My gpu maxes out at 55c when clocked to 940mhz @ 1.15v. I have plenty of headroom.

Yeah...and oops I brain farted there...I meant swap your radiators in your "to be" setup. If you are cooling the CPU first you want the 360 right before the res/pump so that the coolant temp is lowest when it reaches your CPU. Then the 240 should have little trouble removing the majority of the CPU heat for the GPU. Then your flow will be the lowest so stick in your 360 and the coolant will hang out in it slightly longer to get cooled more for the res/pump. Rinse and repeat

At first it will be better, but over time, water will heat and your CPU temps will be just as before.

Don't waste your time.

Even when we are talking about pump efficiency? If my pump is struggling, then perhaps switching the order would help temps and not just temporarily?

IMO, it should be the rads before the blocks.

Pump/res > RS360 > CPU > RS240 > GPU > Pump/res
